(Prior art) Conventionally used wood saws are generally
It has a configuration in which the saw blade is fixed to the tip of the handle, and when the sharpness of the saw blade stops, it has been configured to maintain the sharpness by sharpening the blade, but recently, Due to such troublesome sharpening work, many replacement blade type saws formed so that the saw blade can be replaced arbitrarily with the saw pattern are used. However, in such a replaceable blade type saw, as a means for attaching and detaching to and from the replaceable blade, a "U" -shaped bending metal fitting is attached to the tip of the saw handle.
In most cases, the base of the saw blade is inserted into the gap of the bending bracket so as to be sandwiched therebetween, and the back of the saw blade is received by the bottom of the bending bracket. The configuration has a drawback in that it can be used only for a single-edged saw. (Problems to be Solved by the Invention) The present invention relates to a mounting structure of a saw blade which can be arbitrarily attached and detached even in a double-blade type saw, and has the above-described structure seen in a conventional structure. The goal is to eliminate the disadvantages. [Constitution] (Means for Solving the Problem, Function) The present invention relates to a mounting structure of a saw handle and a saw blade for changing a double-blade type saw into a replaceable blade type. A bending metal fitting having a gap portion into which the end portion can be inserted and having a plate-shaped portion at the tip end is attached to the tip of the handle, and a saw blade locking projection is formed in the gap portion and the plate-shaped portion of the bending metal fitting. When attaching the saw blade to the handle, the hooked portion formed on the saw blade is locked to the saw blade locking projection on the metal fitting, and the saw blade is received and fixed by the projection formed on the plate-shaped part of the metal fitting. When removing the saw blade, the saw blade is bent so that the receiving fixed state can be released. (Embodiment) An attachment structure of a handle and a saw blade according to the present invention will be described with reference to the drawings.
As shown in the figure, the handle 2 includes a handle 2 having a metal fitting 6 attached to a tip end thereof, and a saw blade 3 having hook portions 10 and 11 formed on a base. When the saw blade 3 and the handle 2 are attached,
This is a schematic configuration in which the engaging portions 10 and 11 formed on the saw blade 3 can be fixed by engaging the saw blade engaging projections 7 and 8 of the metal fitting 6. That is, as shown in FIG. 1 and FIG.
The fitting 6 is attached to the tip of the fitting, and as shown in FIGS. 3 to 5, the fitting 6 has a mounting portion 12 with the handle 2 and a gap portion into which the saw blade 3 can be inserted. 4 and a plate-shaped portion 5 having no gap portion, and the gap portion 4 is formed with projections 7 arranged in a crosswise manner, Since the saw blade locking projection 8 is also formed on the side of the part 5, the attachment with the handle is performed by pushing the attachment part 12 with the handle into the tip of the handle 2. is there. In addition, as shown in FIG. 6, the protrusions 7 and 8 in the gap portion 4 and the plate-shaped portion 5 can be formed by extruding the metal fitting 6 by press working, or by melting another member. It is also possible to form them by attaching them, and as another embodiment of the projections 8 formed on the plate portion 5, as shown in FIG.
It is also possible to adopt a configuration in which a plate-like projection 8 having a rising shape is integrally formed on the edge of the plate-shaped portion 5 and the edge of the saw blade 3 is directly received and fixed. As shown in FIGS. 1 to 6, the saw blade 3 is a double-blade saw having both horizontal and vertical grinding teeth cut into a single saw blade. At the same time as the mounting portion 14 is formed, the mounting portion 14 has a hooking portion 10 having a shape corresponding to the positions of the protrusions 7 and 8 formed on the metal fitting 6.
11 are formed. Ona
In the case where the metal fitting 6 is configured as shown in FIG. 7, the engaging portion 11 of the saw blade 3 is unnecessary. Although the structure for mounting the saw blade and the saw handle according to the present invention is as described above, when mounting the saw blade on the saw handle, the end of the mounting portion 14 of the saw blade 3 is inserted into the gap 4. By inserting the hook, the hooking portion 10 is hooked on the projection 7 and, at the same time, the saw blade 3 is rotated while being slightly bent so that the hook 8 on the metal fitting 6 and the hooking portion 11 on the saw blade 3 are aligned. And then release the bent state, and the saw blade 3
When the saw blade 3 is removed, the saw blade 3 is slightly bent, the state in which the saw blade 3 is received by the projection 8 is released, and then the saw blade 3 is rotated in the opposite direction. [Effect] (Effect of the Invention) The mounting structure of the handle and the saw in the replaceable blade type saw according to the present invention has the above-described structure, and the base is slightly bent by attaching and detaching the handle and the saw blade. At the same time, when installed, the saw blade 3 is securely fixed to the metal fitting 6 in any direction. There is an advantage that it can be adopted even in a saw.
